Charter for Working Group

The Session Recording Protocol (SIPREC) working group is chartered todefine a SIP-based protocol for controlling a session (media) recorder.

Session recording is a critical requirement in many business communications environments such as call centers and financial trading floors. In some of these environments, all calls must be recorded for regulatory and compliance reasons. In others, calls may be recorded for quality control, business analytics, or consumer protection. Recording is typically done by sending a copy of the media to the recording devices. The working group will determine requirements and produce a specification for a protocol that will manage delivery of media (including audio, video, MSRP instant message sessions, and real-time text), in SIP-based systems from an end-point that originates media, or that has access to it, to a recording device. PBX and recording vendors today implement proprietary, incompatible mechanisms to facilitate recording. A standard protocol will reduce the complexity and cost of providing such recording services.

The Session Recording problem presents certain unique requirements that are not addressed in the current SIP protocol specification. These include requirements such as the need for a distinction between the session that is being recorded versus the session that has been established for recording.

Privacy and security of conversations are significant concerns. The working group will make sure that any protocol specified addresses these concerns and includes mechanisms to alert users to the fact that a session they are participating in is being recorded. In addition the working group will take account of RFC 7258 concerning pervasive monitoring.

The working group must take care that the session recording requirements and protocol does not conflict with the IETF statement on wiretapping contained in RFC 2804.

The SIPREC Working Group will thoroughly identify use cases, provide example system architectures and deployment scenarios, and define requirements.

The scope of the activity includes:

* Recorder Control

* Session metadata content and format

* Security mechanisms, including transport and media encryption

* Privacy concerns, including end-user notification

* Negotiation of recording media streams

The group will define these issues and rationalize with IETF standards and practices. This includes encryption, NAT traversal, operations andmanageability, SIP-enabled firewalls, authorization, and security.

The group will produce:

* Updated Requirements, Use Cases, Architecture draft

* Specification for Session Recording Protocol
